To all whom t may] concern:

Be it known that- I, FRANK E. RUPF, a citizen of the United States ofVAmerica, residing in Hartford, in the county of Hartford and Stateofonnectcuahave invent-- 4ed'a certain new and useful Special'v Carriagefor Testing-Type-Writers, of which the following is a specification.

This invention relates to a carriage for typewriting machines adapted tobesused in-- place o f the regular working carriages when certain partsof 'the machines `are bemg Atested Onadjusted. In testing andv adjusbing operations,.for instance setting the trip of the carriage feed, themachines are raised for access'tol their undersides and lowered I to`their feet inloperating position 'axgreat A v fect Working, 'condi tion.

-I lthe accompanying drawings isillustrated'only so much of atypewriting machine of the'Standard Royal type, .With-the testingcarriage of this invention applied' t thereto, as is necessary to lmparta full understanding of the *construction and mode of-`operationv ofthis invention.'

The testing carriage is, 'in all essential ieatures, similar to theworking carrlage` which it replaces. It comprises a frame 9 inSpecification of Letters Patent.

of the carriage of vthe machinel vwhichit replaces-,with means by whichit' maybe readily attached to the 'machine and withmeans for; connectionto the carriage ringe. being actuated .in all vrespects; i."vfith'injury to the ball bearing races this testing carriage, due tq rouglsihlndling with manipul tingl knobs 11 in Athe usual 'mannen Cnt eunderside of thecarriage frame 9 is formed a ball race 12, the counterball-race being formed 'in the upper surface of a bar 13, and betweensaid races are lo# cated bearing balls 14- in-the usualA manner.

Secured to the underside of bar 13 are rods 15 which extend beyond theends of said bar and are adapted to seat in the ball race 16 of thecarriage shift frame 4 of the machine. 65

The se4v rods 15 are provided with `clampiibg devices conslsting ofblocks' 17 fitted to slide- -on rods 15 and spring jaws 18 secured tothe undersides of the-blocks andadapted to bear on -the underside of theends of the ball race 1'6 when the rods 15 are seated in the ball raceand the blocks 17 slide alongthe means for quickly applyingthe auxiliaryor substitute testing carriagev to any machine when assembled ready tobe tested and to 'have its Aparts adjusted and for removing ittherefromwhen the machine is m proper condition'to receive its workingcarriage. 80

A light braekt 19 extends rearwardly from the lower vball'race bar13 andcarries a roller 20 on which the back bearing bar 21 vof the testingcarrlage rests when the carriage is removed from the machine.- This bar21 occupies the same position, relatively to Vthe otherpaits of themachine, 4as do the back bearing bars of the regular Working carriages,-andis controlled by the roller bearings 8 and 7 when the testingcarriage 90 "is applied to a machine in operative position. Thisltesting carriage is also provided with a. hook 22 for receiving the tapeof the spring barrel and a feed rack 23 which is engaged-by the escapemechanism 24 carried by the bracket 6 of the machine. It will beunderstood that the machine will be op erated in .the .samemanner as itis when in conditionI forV regular use, the testing Liarf regard toitsfeeding movements, in anuinner similar to thefworking carriages,lpar-s l ticularly when used to manipulate the type: bar controllingdevices in' setting and adjusting the trip of the feedingniiechanisin.
